He finally gave up trying to be a telegraph operator.

He opened a little shop.

He invented many things, and kept on thinking.

He could not make his inventions successful, for he had little money.

He thought so hard that he forgot everything else.

Once he was asked to speak before a company.

He forgot all about it.

They sent for him, and found him at the top of a house putting up a telegraph line.

He went in his working clothes to make his speech.

He felt queer when he found a room full of elegant ladies.
